Active-Active Multi-Region DR on AWS for Continuous Uptime

For businesses handling high-value transactions, downtime is not an option. Even a few minutes of disruption can lead to lost revenue, unhappy customers, and reputational damage.

In this success story, we showcase how we partnered with a customer to design an Active-Active multi-region disaster recovery (DR) architecture on AWS, achieving a Recovery Time Objective (RTO) of 5 minutes and a Recovery Point Objective (RPO) of 10 minutes. The result was uninterrupted service, faster performance, and long-term business confidence.

Customer Problem Statement

The customer was running critical applications from a single AWS region, creating both performance and availability risks.

Key challenges included:

• Single Point of Failure: A regional outage could bring applications offline.
• Slow Recovery: Manual recovery processes risked missing RTO and RPO targets.
• Performance Bottlenecks: Users in different geographies faced latency.
• Compliance Pressure: Industry standards required a strong DR plan.

The leadership team needed a solution that protected revenue, improved resilience, and satisfied compliance.

Solution Implemented

We built a multi-region Active-Active DR strategy across Mumbai (primary) and Hyderabad (secondary) regions. Both regions ran workloads in parallel, ensuring rapid failover and continuous operations.

Key elements:

• Automated Traffic Management: Route 53 redirected users within seconds of a disruption.
• Application Continuity: ECS/EKS clusters ran across both regions and were kept in sync via CI/CD.
• Data Resilience: MongoDB Atlas global clusters delivered an RPO of 10 minutes with automatic failover.
• Content Delivery: CloudFront with S3 replication ensured static assets were always available.
• Governance: AWS Secrets Manager and CloudWatch provided secure, centralized monitoring.
  This design ensured an RTO of 5 minutes and continuous business performance.

Thinking about building a multi-region DR setup for your own workloads? Our AWS architects can assess your current environment and show you how to achieve sub-5-minute recovery times.

Business Value Achieved

The Active-Active setup delivered measurable outcomes in just weeks:

• 100% uptime maintained during failover tests.
• RTO reduced to 5 minutes, enabling near-instant recovery.
• RPO of 10 minutes, protecting transaction data.
• 100% compliance alignment, meeting regulatory standards.

Driving Business Growth

The impact extended well beyond IT:

• Revenue Protection: No transaction loss during failovers.
• Customer Trust: Always-on service improved loyalty.
• Scalability: A multi-region foundation prepared the business for expansion.
• Efficiency: Automation freed teams from manual recovery.
• Competitive Advantage: Resilience became a clear market differentiator.

By adopting an Active-Active multi-region DR strategy on AWS with a 5-minute RTO and 10-minute RPO, our customer turned disaster recovery into a business enabler. The company now delivers uninterrupted service, protects revenue, and grows with confidence in an unpredictable world.
